Predation On Furbearers And Management Alternatives, Ronald D. Andrews

Great Plains Wildlife Damage Control Workshop Proceedings

Most of the presentations from other members of the panel have discussed direct predation of one animal upon another with evidence and data to support it. Their presentations indicate that in some instances, considerable data has been collected that substantiates the fact that predation has been and can be a limiting factor in sustaining certain local animal populations. Suggestions have also been made concerning management alternatives that might help to reduce this predatory impact when desirable. Predation on furbearers and its impact is considerably more ambiguous and abstract. Facts and data concerning significant predation on furbearers, except for mink on …

Youth Fur Harvest Programs, Edward K. Boggess

Great Plains Wildlife Damage Control Workshop Proceedings

Youth fur harvest programs in Kansas have been developed as one phase of an overall series of youth education projects on ecology and the environment. Currently, the series includes Ecology, Acres for Wildlife, Kansas Mammals, Birds Around You, Reptiles and Amphibians, Fur Harvest, and Fishing. Basically, the fur harvester project was developed because, although many young people in the state are interested in trapping, few good sources of information or instruction were available to most young trappers. Because many objectionable trapping abuses are unintentionally caused by young or inexperienced trappers, it was hoped that this project would encourage ethical and …

Aspects Of Reproduction And Population Dynamics Of Bobcats In Wyoming, Douglas M. Crowe

Great Plains Wildlife Damage Control Workshop Proceedings

Distribution of the bobcat includes the 48 contiguous United States and limited occupance of southern Canada and northern Mexico. There are 11 subspecies, the one in Wyoming being Lynx rufus pallescens. Bobcats inhabit an amazing variety of habitat types, from northern boreal forests, southern swamp, and cane regions to the below sea level desert of Death Valley, California. Throughout this vast area, they utilize a wide variety of prey species. One study in Wyoming revealed at least 18 different species in the stomachs of bobcats; the cottontail rabbit being predominant. A similar study in New England revealed 20 different …

Coydogs In Nebraska, Brian R. Mahan

Great Plains Wildlife Damage Control Workshop Proceedings

Skulls of 44 suspected coyote (Canis latrans) x dog (C. familiaris) hybrids, "coydogs" were collected in Nebraska from September 1975 through April 1976. Each skull was compared statistically with skulls of known coyotes, dogs, coydogs, gray wolves (C. lupus), and red wolves (C. rufus) for identification. Thirty-two males were identified as: 5 coyotes, 2 dogs, 25 coydogs; 12 females were identified as: 4 coyotes, 2 dogs, 6 coydogs. Three concentrations of hybrids were located in southeastern Nebraska.

Skunk Rabies Control And Surveillance In Central And Eastern Montana, Gary Nesse, Kenneth Seyler

Great Plains Wildlife Damage Control Workshop Proceedings

A skunk rabies control and surveillance program was initiated by the Department of Livestock, Vertebrate Pest Control Bureau, within designated areas of Fergus, Fallon and Richland counties between January 1, 1975 and July 30, 1975. The use of strychnine eggs employed by trained, licensed government pesticide applicators plus cooperation of local citizens proved to be a safe and selective method for conducting such a program. Of the 83 skunks diagnosed rabid by the Fluroescent Antibody Test as the Department of Livestock Diagnostic Laboratory in Bozeman, 72 percent were taken from control areas; however, of 284 skunks examined from control areas, …

Coyote And Dog Depredations, Joe Schaefer, Ronald D. Andrews

Great Plains Wildlife Damage Control Workshop Proceedings

The objective of this study is to determine the impact of coyote and dog depredation on the sheep industry in southern Iowa and to evaluate the livestock husbandry practices associated with these losses. In order to obtain background information on sheep management practices and the number of alleged livestock losses caused by coyotes and dogs in southern Iowa, a questionnaire was sent to 3,173 sheep producers. Sixty-nine percent of the 1,260 respondents indicated that they did not have any problem with coyote depredations during 1975. However, the major cause of mortality was reported to have been coyote predation which accounted …

Predation On Big Game And Its Management, Samuel L. Beasom

Great Plains Wildlife Damage Control Workshop Proceedings

This paper summarizes information from the literature and personal observation to present an overview of the effects of predators on big game populations. Specifically it examines control of prey populations, culling of inferior prey, and stimulation of prey productivity. Food habit investigations were omitted because of the impossibility of evaluating the impact of predation by this approach because of a lack of population data.

Prairie Dog Management: Educational Assistance To Local Governmental Units, Edward K. Boggess

Great Plains Wildlife Damage Control Workshop Proceedings

There is a long history of involvement between Kansas State University (formerly Kansas State Agricultural College) and township governmental units regarding control of prairie dogs. In 1901 and 1903, the Kansas legislature passed laws authorizing townships to conduct prairie dog control programs and providing funds for the College to conduct experiments on methods of controlling prairie dogs and gophers. The acts also directed the College to procure and furnish to the townships the proper prepared materials for prairie dog control. The Experiment Station began supplying strychnine baits in January of 1902 and continued this practice until 1970.

Hydraulic Resistance Of Grass Media On Shallow Overland Flow, David K. Tao, Billy J. Barfield, Austin E. Lyons

KWRRI Research Reports

Simulated dense vegetation with random blade arrangements and different blade flexibilities were used to determine the hydraulic properties of flow of small, non-submerging depths. With the water flowing among the randomly patterned vegetation blades, drag resistance becomes the dominant force that retards the flow. An equation of flow was established based on the momentum balance in the system. Experimental results were used to determine the coefficient of blade resistance, R_D, and plotted in terms of blade width and flow depth Reynolds number respectively.
